Abstract
A display device including a scanning circuit formed using single conductivity type thin-film transistors suppresses threshold changes in the thin-film transistors forming the scanning circuit by controlling a circuit for maintaining an internal node of the unit circuits forming the scanning circuit at a constant potential is controlled by a clock signal or a pulse signal having a smaller amplitude than the amplitude of an output signal.
